I saw prime magic squares mentioned (see puzzle
68, in these pages) in 'Mathematical Recreations' in Scientific
American near the end of the 80's. I spent that summer playing around with
algorithms to generate primes and prime squares, along with Channon
Price. We generated the algorithm and a 41x41 square. Since then I've
been mostly working at Microsoft, on NT 3.1, Windows 2000, and now Flight
Sim. (More personal info in his Web page)
